Summary Compared with traditional geometric modeling techniques, image‐based modeling technology has the advantages of simple operation, quick reconstruction, and strong sense of reality. Compared with the three‐dimensional scanning technology, it has the characteristics of low cost and simple algorithm. In a broad sense, the image‐based 3D modeling technique not only includes the geometric modeling of the entity but also includes visual restoration, ie, reconstruction of the geometric model of the entity using the image, and restoration of its corresponding surface texture, reflection properties, lighting conditions, and the like. This paper focuses on the application of geometric reconstruction methods to study the application of VR computer images in the three‐dimensional virtualization of sports human science. By combining the background difference method and the interframe difference method, the target region where the moving human body is located can be accurately extracted from the video, and then the idea of the human body can be divided along the virtual plane. Finally, the end‐point feature points of the human body are determined by the geodesic distance, and a three‐dimensional model skeleton is buried using a discrete penalty function, and an image‐based three‐dimensional reconstruction system is realized.
